Optima L4-2.4L (2001)
Safing Sensor: Description and Operation
Arming sensor/safing sensor: The arming/safing sensor built in the airbag firing circuit has the function of arming the airbag circuit under all required
deployment condition and maintaining the airbag firing circuits unarmed under normal driving conditions. The safing sensor is a dual-contact
electromechanical switch which closes if it experiences a deceleration exceeding a specified threshold.
Back-up power: The SRSCM reserves the energy supply to provide deployment energy for a short second when the vehicle voltage is low or if lost in a
vehicle frontal crash.
